Dr. Leo Cohen's chosen specialty occasioned certain... occupational hazards. No more proximate an example of this truth could be afforded than the tableau now before him of the Nordquist twins, tall and toned monozygotic teenagers of a striking and stereotypical Nordic phenotype.

Their father had had to transport them of course, they being too young for driving licenses, but per the Doctor's strict protocols, Mr. Nordquist had not remained to await them, not even in the office foyer that served, when needed, as a patient-only waiting room. Patients' sponsors -- fathers, uncles, stepfathers, close family friends, almost to one male and much older than the patient herself -- were all of course well aware of the intimate and unorthodox nature of the therapy Dr. Cohen provided, but they were never allowed to tarry on site during its application.

This regulation was necessary to preclude any disruption of the procedures by men too well accustomed to crossing boundaries, arrogantly, and at will, with these same young ladies. Of course, Dr. Cohen fully endorsed and supported these sponsors' sexual privileges with respect to their young wards, anywhere, that is to say, but within the sanctuary of his clinic during treatment sessions.

The rule's steadfast enforcement also logistically freed these men to safely task, with confidence, the girls' unwitting mothers, aunts, and so on, with the duty of conveying the precious bundles into the good doctor's care without risk of an unfortunate revelation and regrettable misunderstanding -- or rather, regrettable understanding -- of the true state of affairs. These otherwise cautious maternal figures were mollified with respect to their own exclusion from the clinic by rule's universal application and acceptance.

The relevance of these provisions to present circumstances was that always, during actual treatment sessions, the entire facility was populated solely by Dr. Cohen and his patient, or patients.

And in this instance, the plural applied. The Nordquist girls, Anya and Darya, were fifteen. Blonde -- everywhere. Pink. Cute tits, slightly larger on Anya but perky and petite in either case. And naked, a state change effected with alacrity upon the doctor's instruction. And hence, the occupational hazard, in point: Dr. Cohen spent most of his day in a state of sexual distraction and plain old horniness. That morning's session with the delectable Bethany Michaels had left him stiff and unrelieved; the memory of her mewling orgasm under the influence of biofeedback-driven stimulation panties was haunting him even now.

And following Bethany, an introductory session with a new patient, a ginger-haired darling named Prudence Parker, had left him anxious to get to know the youngster much, much better. Prudence was a Track B patient, less common than patients like Bethany or the Nordquists, who had all been Track A cases upon arrival. Track B patients entered treatment as complete innocents, for whereas Track A girls needed a "reconstructive conditioning" protocol to adjust their negative or at least suboptimal response to already-in-progress sexual molestation, Prudence, in contrast, had no idea that her maternal Uncle's purpose in bankrolling her "counseling" was one of "constructive conditioning." The cute little redhead had, as of this morning, never even seen a rampant adult cock and, based upon the subtle introductory interview, was still largely free of even the most basic pubescent sexual ideation. And yet, if Dr. Cohen's Track B protocol proceeded apace, within six weeks the adorable adolescent would be taking uncle-cock hard, deep, and regularly -- and fully convinced that the seduction had been entirely of her own initiation and doing. Indeed, another cause of this day's aforementioned occupational hazard: the imagined vision of that fresh-faced middle-schooler soon being power-fucked by an uncle three times her age added to the ache in the diligent doctor's testicles.

And now he must endure this session with the Nordquists, who were quite far along in the optional follow-on "Track C" program.

Both of these athletic blondes had been through Track A treatment, separately, shortly after their simultaneous menarche. This had made for an interesting case study, because while both girls were conditioned over the same time period, their sessions had of course been separate and, furthermore, neither girl had been aware of the other's concurrent involvement. Of course both girls had already been subject to their predatory father's unwelcome and ongoing sexual use by that time, but each had believed she was experiencing private, and unique, misfortune.

Perhaps he would write a paper on the similarities and differences between the twins' treatment response trajectories for the "edutainment" of his colleagues and the advancement of their cutting-edge mental health discipline. One twin, Anya, had been initially the more poorly adjusted to her situation, but before the biofeedback program had run its full course she had surpassed Darya in the pace of her realignment.

In any case, both girls were now thoroughly conditioned under Track A, and had adapted quite well to serving as pleasure-objects to their shamefully narcissistic father. Once they each had become his willing and even eager sexual partner, Mr. Nordquist had revealed to them their common situation, purpose, and usage, and now he often sought his fatherly gratification with the two girls in concert. If Dr. Cohen understood correctly, it was Mr. Nordquist's intention to personally breed both girls within the next couple of years, which might necessitate some preparatory Track E conditioning, but in the meanwhile, he desired that they be next conditioned toward a different objective, one to enhance his immediate enjoyment, and so here they were.

It was no surprise to the veteran clinician that both girls were now very happy providing and even applying their youthful bodies to the service of their father's personal lusts, nor that in the course of these explorations Mr. Nordquist had often required them to entertain him with Sapphic displays of girl-girl sexual disportment. Naturally, they did their best to satisfy his demands in this regard, but their enthusiasm in the task was not where he, nor any red-blooded heterosexual male with seemingly unrealistic whim gratification expectations, would feel it ought to be.

But seemingly unrealistic whim gratification expectations were not so unrealistic to those patronizing Dr. Cohen's practice, and so the over-sexed and over-indulged -- and sufficiently well-heeled -- pillar of the community had enrolled his girls in one of Dr. Cohen's follow-on programs, Track C to be precise, a biofeedback protocol specifically tailored to the task of turning otherwise-heterosexual young girls into avid and visually entertaining cuntsuckers. This service's low alpha-designation, coming immediately after the two introductory programs, Track A and Track B, was a testament to the universal popularity and appeal of juvenile lesbian behavior among gentlemen of discernment.

Anya was by now fully engaged in the afternoon's exercise, wearing a pair of stimulation panties that rewarded her, clitorally, each time the system detected a positive nervous-system reaction to her current activities -- which happened to be the vigorous oral servicing of her twin sister's smooth vulva. Dr. Cohen was pleased to note on his screen readout that both the girl's feedback graphs and the stimulation panties' reward counter indicated that she was now very much taking direct personal pleasure from dining upon her sister's responsive young cunt, experiencing "self-reward" in advance of those administered by the system. The past few weeks of Track C biofeedback had successfully turned cunnilingual compliance into authentic avidity.

Darya, too, was enjoying the experience, receiving, in addition to the obvious rewards of her sister's now-practiced mouth at work upon her sex, additional biofeedback-triggered vibrational rewards through the agency of a bluetooth-connected anal device -- to wit, a therapeutic butt plug. As the receiving patient in this regimen today, Darya wore a visor which bombarded her attention with imagery of lesbian pornography, of her sister in sexual poses, and of a wide variety of engorged young pudenda. Whenever the system detected the sweet blonde responding with pleasure to any of these conditioning cues, it provided, within her broader pelvic region, a rectally-centered vibrational reward. Much like her sister, Darya was earning many such rewards on this particular afternoon.

Watching this display, of course, did nothing to assuage the taut need in the therapist's own sexual apparatus, and so, with his office hours drawing to a close, Dr. Cohen adjusted matters to prepare himself to finally address his vocationally-induced discomfort.

He rolled back his chair a couple of inches and looked down into a pair of large, dark, expectant eyes. Well aware of the phenomenon that ensures any girl looks beautiful while she is sucking on one's cock, the Doctor nonetheless took additional note that Esther Mueller's face was beautiful to begin with -- remarkably so.

Her dutiful, seemingly adoring eyes, already mentioned, met his steadily, maintaining appropriate contact throughout the long, slow, slick cycle that her thick, sexy lips repeatedly described up and down his delighted penile shaft. High cheekbones. Elegant, wispy eyebrows. Smooth, radiant skin. Silky, shiny, black hair--almost blue -- framing it all. And yes, this lovely visage was made all the more entrancing to the man by its present service upon his over-teased cock.

Esther was the third of Reverend Mueller's daughters to come through Dr. Cohen's care, and to his taste, the most delightful yet. Spaced about four years apart, each had in turn been enrolled as innocents in Track B, each had then entered into the role of pleasuring her father, and each had subsequently gone through the doctor's favorite of all conditioning programs, Track D, in which the patient is adjusted through biofeedback protocols to enjoy -- in fact, to seek out -- every and any opportunity to sexually service anyone to whom it might please her sponsor to direct her.

Reverend Mueller was on this very day back in Korea, at the rural orphanage run by his protestant denomination, selecting yet another adoptive daughter. While most would-be parents seek infant adoptees for bonding reasons, and despite the fact that children adopted when older often exhibit behavioral and emotional problems, the admirable cleric believed that these considerations were far outweighed by the benefits of being able to judge the future teenaged beauty of an eight- or nine-year old prospective adoptee.

The attentive upturned countenance between Dr. Cohen's spread hairy thighs validated this theory, for as a nine-year-old orphan, Esther's adorable face had accurately foretold her fourteen-year-old beauty. And as to any behavioral or emotional issues that might accompany a late adoption, well, that was of course something that biofeedback conditioning was specifically able to address. As her continued deep cock-worshipping efforts so clearly attested, at this moment at least Esther Mueller's behavior was, in Dr. Cohen's judgment, quite exemplary.

So, yes, every four years or so Reverend Mueller selected another lovely preteen girl and adopted her into his very happy family. Of course, no sexual conditioning was begun with a girl prior to menarche -- Reverend Mueller would be aghast at the very notion of abhorrent, pedophilic activity, and Dr. Cohen himself was of the professional opinion that any pre-pubescent conditioning of a sexual nature was in the very least highly unethical. Both men, happily, viewed matters completely the opposite at the onset of puberty, and so here Esther was.

Today, while the fourteen-year-old was engaged in mutually satisfying oral engagement with her therapist, her oldest sister Ruth, also a Korean adoptee, was twenty-two and about to graduate from her pre-med course at Yale. Middle sister Naomi was eighteen, and had been accepted into Dartmouth for the coming fall. Just in time, Esther was finishing the treatment protocols which would prepare her to take Naomi's place in the exceedingly popular Daughter-Share program in which many of Dr. Cohen's patients eventually were enrolled by their variety-seeking sponsors.

For a man to enjoy this selective club, he must of course provide a suitable daughter (or ward) to share; further, this young girl must undertake Track D conditioning, as Esther was soon to complete. Once one's own girl was in the pool, one could "check out" a playmate much like a library book. Dr. Cohen had no daughter or niece or similar to share, but of course given his trusted position, no member would have dreamed of denying him access to such a fine stable of teenaged girlflesh. In fact, as the doctor looked down into the girl's lovely Asian face, he recalled having enjoyed her big sister Naomi's athletic young vagina only the week before.

Reverend Mueller was indeed a prudent and wise man to be even now selecting Esther's own successor for the Daughter-Share pool, some four or five years before she would even be needed or trained. In the meantime, Dr. Cohen was certain that Esther would be quite popular in the Daughter-Share Program, as had been both of her sisters before her.

So it is easy to understand why Track D was Dr. Cohen's favorite protocol to undertake. Not only did it result in fresh selections within the Daughter-Share pool to which he enjoyed ongoing privileges, but of all the tracks, its execution was easily the most directly gratifying to the practitioner himself. Today, they were working on honing some fine points in Esther's oral conditioning, but the entire track included extensive vaginal and anal biofeedback exercises, in which Dr. Cohen's own sex organ was most often the primary training tool. As his colleagues like to joke among themselves, "Track D is more than just getting your dick wet -- but that ain't bad, either!"

Dr. Cohen himself had co-authored the seminal paper on the Track D protocol, entitled "Transference of Phallus-Specific Devotion." A layperson might suppose that the most difficult conditioning would lie in converting a victim of sexual abuse into a devoted sexual servant to her own abuser. However, as this paper affirmed through extensive literature review, this was in fact rather straightforward. Young females are pre-wired, prior to any conditioning, to become attached to the man attached to the particular penis she receives, willingly or otherwise. In fact, Track A was second only to Track B -- that of conditioning the never-before-abused -- in its simplicity and success rate.

Dr. Cohen's important paper, and the Track D protocols developed from it, addressed the far trickier conditioning problem of moving a girl from happy devotion to her father's, stepfather's, uncle's, guardian's, or whoever's specific penis to those of many different men, and effecting this change without upsetting the girl's emotional well-being. For this reason, Track D conditioning was a "must" prior to entering a girl into the Daughter-Share "lending library."

Esther was going to have no problems in the Daughter-Share program. She had taken to phallic heterogeneity quite naturally, and this had allowed the therapist to fine-tune her conditioning with a few extra, advanced experiences. Like all Track D patients, she had been conditioned to respond positively to the flavor of pre-cum. Like most, but not all Track D girls, her body had been trained, through biofeedback, to orally edge a man indefinitely. In fact, she was practicing that right now. Sensors tracking Dr. Cohen's own biofeedback readings interacted with the girl's apparatus, rewarding her each time she successfully brought him close to orgasm, but not quite. In this protocol, the patient initially received signals of impending penile climax, rewarding successful approach and denial with the proven agency of clitoral stimulation.

Over time, the preparatory signals to the patient were reduced and delayed, so that she learned to manage "the edge" based solely on the signals her now-trained senses interpreted from the penis itself. Esther had already taken to this process quite well, and today she had kept the good doctor within a cunt-hair of coming for most of the past hour.

As a result of this "vicious" teasing, on top of the underlying occupational hazards attendant to his vocation on this and every other day, Dr. Cohen was now wound into a very coiled state. He was ready to come, furiously. He had enjoyed the day's entertainments: Bethany, suffering from the sudden denial of her stepfather's cock; Prudence, who had no idea how energetically her "gentle" uncle would soon be ravaging her as-yet virginal pubis; the Nordquist twins, who even now were enacting a scene most men only dream of seeing in real life; and of course Esther Mueller, of the gorgeous complexion and talented mouth. But now he needed to unload. As was his habitual daily practice, he had denied himself relief until his work was done, and now it was. The twins' and Esther's parallel sessions were nearing their scheduled termination time, and he had no more patients for the day, so he could at last address his own delicious condition.

He was going to allow himself to come, and of course he knew where: straight down Esther Mueller's practiced throat. But after a day of so much stimulation, who should be his climactic muse? What girl should he focus on as he erupted in what would surely be a prodigious ejaculation?

He looked down at Esther. Staring into her worshipful eyes as he released would be wonderful. In fact it had been, yesterday. Ah yes, but that was just it: he had come in young Esther's "honor" just the previous afternoon.

He looked up, over his desk, at the now sixty-nine-ing Norquist twins. In their passion, they had practically forgotten their health care provider's presence, and were completely unaware of his under-desk patient. They were magnificent, and no straight man can treat teenaged lesbianism with pedestrian indifference; for the record, Dr. Cohen was indeed a decidedly straight man. But as is often the case in the practice of prolonged edging, the stimulant that torments a man's aroused imagination to the brink is often best replaced at the final moment by a fresh object of sexual focus.

Impatiently, he opened a file on his screen, and found the cute face of his newest patient, the (still) innocent ginger-haired Prudence. Yum. To come while imagining himself painting that adorable countenance with his middle-aged spew was an enticing prospect, but upon reflection he decided that spoiling, in even this artificial way, any aspect of his forthcoming "discovery" period with the adolescent cutie wouldn't be worth it, in lost future delight.

Then, of course, it came to him, and once bidden it seemed the most obvious solution. Bethany.

Bethany, his favorite, and soon-to-graduate, Track A patient. Bethany, who had spent this week in sexual frustration, coming and coming to conditioned stimulations but who had, inexplicably to her, been suddenly denied the habitual sexual congress with her previously-despised stepfather, the man who would, on the morrow, finally break her fast in what should be a watershed moment for the delightful teen. Yes, he would come "to Bethany."

It was simple matter for Dr. Cohen to pull up appropriate video, for the consulting-room's recording infrastructure would put MGM and the NSA both to shame. Here it was, a perfect twelve-second loop, of the pretty brunette climaxing in her training panties that very morning, her half-lidded eyes and pinking cheeks telling the tale, her own hands pinching her sweet bra-less nipples through the fabric of her thin top. In the doctor's opinion, the now-vaginally-starved teenager’s tit-play was completely unconscious, driven by her body’s own autonomic need. Gorgeous.

He put the loop on full screen, and unbeknownst to both the twins and to his fellatrix, Leo Cohen focused his vision on the repeated writhing of the astonishingly sexy Bethany Michaels. Ready, he gently put his hand upon the back of the head under his desk, signaling his intention. At the signal, Esther swallowed Leo's not-undersized phallus to the root, filling her protesting but thoroughly-trained esophagus, and as conditioned in response to a "forced" deep-throat, the lovely Korean-American experienced a submissive, no-touch orgasm within her own pelvis.

As her throat fluttered in both protest and orgasm around his ministering meatpole, this unsung hero of humane arts finally allowed his tormented genitalia their long-denied release.
